AMETHYST
What is
Amethyst
Amethyst is Purple or Violet shaded quartz gemstone. It is a form of Quartz and comes in different hues of Purple.
As it is a
variety of Quartz crystal it is made from Silicon Dioxide and its
Purple shade is because of impurities Like Iron and in some cases some
other elements or Transition metals.
Amethyst is
a semi-precious gemstone but, till 18th century Amethyst was
considered a precious gemstone. It was said to be a part of “Cardinal”.
Cardinals are said to be the most precious
gems which are Diamond, Sapphire, Emerald and Ruby. Until a large
deposit of Amethyst were found in Brazil and it lost its value as precious gem.
Amethyst has
a rich history and is said to have a tail of more than 2000 years. It
was valued a lot and was considered to have mystical powers. Greek considered
it a powerful stone against drunkenness.
Tibetans made beads of Amethyst and gave it a
very sacred value and relate it to Buddha. In Middle Ages it was
a symbol of royalty. Medieval European soldiers use to wear Amethyst,
believing it keep you cool.
Ancient
Egyptians and Romans used Amethyst for “Intaglio Engraved Gems”, which means
that the single side of the stone was engraved with some image of a personality
or Inscriptions.
Romans king Caracalla
(Commonly known as Antonius, was emperor from 198 to 217) image was found
engraved on Amethyst in the treasury of Sainte-Chappelle.
Amethyst are
found in Geode, which are said to form when Gas bubbles get
trapped in the Lava and when it cools and hardens around trapped bubbles.
These bubbles
form Cavities in which Amethyst is formed. These bubbles can range from microscopic
size to feet’s long.
After the
formation of Cavities, process of Crystal Formation takes place. It is
said that the Salt Water which enters the lava moves in the cavities. As
salt water contains Silica and other minerals that it bring along
with it.
Then with
passing Thousands or Millions of years pressure and reactions form crystals
within the cavities. It’s not only Amethyst that is formed but, layers are
formed of different elements e.g. Celadonite, then Agate, then Quartz and
finally Amethyst is formed.
Amethyst is
a stone of February. It takes its place at 7 out of 10 on Mohs
Hardness Scale.
Though

instead of Carats. Amethysts are often given names like Plum colored,
Lavender colored, Rose colored, Raspberry or Grape colored.
If Amethyst is in its Rich shade of Violet
with a slight tint of Blue it is considered very valuable, rare and
can be priced very high.

Prasiolite
or Green Quartz (sold as Green Amethyst)
There is no such thing as Green
Amethyst. It’s a word used by dealers, which is not a true statement and is
a misleading name.

strictly forbidden such moves, for instance, Yellow brownish colored quartz is
sold by calling it “Citrine” or “Yellow Emerald”. P.s there is no such thing
as Yellow Emerald.
Same goes
with Green Amethyst there is nothing known as Green or Pale Green
Amethyst. An Amethyst naturally or mostly synthetically is produced by passing Amethyst through
“Heat Treatment or Irradiation” process to change its color.

Celsius, Amethyst color is forced to change and takes the Greenish shade
which is said to be Prasiolite or Green Quartz not Green Amethyst.
